In 2135, NASA says an asteroid the size of the Empire State Building could slam into Earth.According to the Washington Post, scientists say, though the chance is small, the asteroid could slam into Earth on September 22, 2135, destroying lots of living things on the planet.The odds of the asteroid, named Bennu, actually hitting Earth are one in 2,700. If the asteroid does get too close for comfort, the geniuses at NASA have hatched a plan.NASA says they could send a nine-ton “bulk impactor” to push the asteroid out of Earth’s orbit. The plan is called HAMMER, which stands for (deep breath) Hypervelocity Asteroid Mitigation Mission for Emergency Response.Though the odds are slim that the massive asteroid will hit Earth, in 1908, what is believed to be an asteroid crashed in Siberia with force 185 times as powerful as the bomb dropped on Hiroshima.The impact flattened 80 million trees and killed hundreds of reindeer. Scientists say Bennu isn’t all bad.The asteroid is giving scientists a chance to test theories. NASA’s OSIRIS-Rex will also map Bennu and figure out what the asteroid is made of.To learn more about Bennu, click here. 1153

Hurricane warnings are up for some of the Louisiana gulf coast as Hurricane Delta is expected to cross the Gulf of Mexico and strike the state later this week.Hurricane Delta made landfall on Mexico's Yucatan Peninsula Wednesday morning and the National Hurricane Center (NHC) expects the storm to continue moving northward and bring "life-threatening" storm surge to the Gulf Coast late this week.According to the NHC, Delta made landfall near Puerto Morelos, Mexico with 110 mph winds, making it a strong Category 2 storm. The Yucatan Peninsula is home to many Mexican resort towns, including Cancún and Playa del Carmen. Belize, a coastal country on the southern part of the peninsula, may also feel effects from Delta.Hurricane Delta weakened to Category 1 status after it emerged off the Yucatan Peninsula into the Gulf of Mexico Wednesday afternoon. As of the 10 p.m. CT Wednesday advisory by the NHC, Delta had top winds of 90 mph.The storm is expected to regain major hurricane status on Thursday, but make landfall as a Category 2 hurricane on Friday somewhere along the Gulf Coast. A hurricane warning was issued late Wednesday for areas from the Texas/Louisiana border to Morgan City, Louisiana. While the center of Hurricane Delta is not expected to be as intense as when the storm had peak winds of 145 mph on Tuesday, the National Hurricane Center expects the storm to grow in size, spreading the impacts over a wide area of the coast. The National Hurricane Center said the growing hurricane will likely increase the storm surge and wind damage threats. Louisiana has taken the brunt of the impact of the 2020 hurricane season. Hurricanes Marco and Laura have already made landfall in the state, causing inland flooding and significant damage along the coast. Hurricane Sally also did significant damage nearby Gulf Shores, Alabama, when it made landfall in September.Between Monday afternoon and late Tuesday morning, Delta exploded from a tropical storm into one of the most powerful hurricanes of an active 2020 season. Only 2005 (with 28) has seen more named storms than the 25 totaled so far in 2020. 2128

If we're sick, we don't think twice about seeing a doctor. Health experts say we need to start looking at obesity the same way. One woman has turned her life around. And as she's lost weight, she's gained so much more."We're grazers," Marcie Weiler recalls. "I was brought up just (hands to mouth motion) mindlessly. Totally mindlessly just pop it in."That's how Weiler grew up thinking about food. And after a few serious injuries?"My coping mechanism was soda pop and food of course," Weiler says.At her heaviest, she weighed 300 pounds."I just thought, 'Oh my God, I'm going to keep getting bigger,'" Weiler saysShe's not alone. Obesity rates in the United States are at all time high. 40 percent of all Americans are considered obese and 20 percent morbidly obese."It affects cardiovascular health," says Dr. John Weaver, a general and bariatric surgeon with Presbyterian / St. Luke's Medical Center. "It affects you know pulmonary health and diabetes it affects joint pain and problems."Dr. Weaver says the effects can be serious, and potentially deadly. A new study found improvements in mortality rates are slowing, obesity is the main cause, and many people look the other way."Only 20 to 30 percent of people who are obese had even talked to their doctor about their obesity," Dr. Weaver says. "And the problems that go along with being obese."Dr. Weaver says it is possible to be overweight and healthy, but your body mass index can let you know for sure. And once you've figured that out, beating obesity isn't just about cutting calories and working out. There's a new understanding that the biggest challenge, is revamping your lifestyle."It's an entire body change," Dr. Weaver says. "It's not just an eating habit it's changing your eating habits but it's changing how you perceive food. And everything that goes along with food."That's what Weiler has done. Along with bariatric surgery, she has lost more than 100 pounds. But that's not the only thing that's changed."My general opinion of myself," Weiler says.Reversing a trend, for a healthier and potentially longer life. 2099

In a few weeks, thousands of college students will begin their yearly right of fall by returning to the campus of Tufts University in Medford, Massachusetts, but a return to campus life this year will mean testing and quarantining for those students who chose to come back.Like colleges and universities across the country, Tufts is experimenting with a new plan that will allow more than 5,000 students to come back to campus while at the same time, instituting rigorous new guidelines in an effort to keep COVID-19 from spreading.The key to success, testing.“We wanted to test for COVID at a frequency that would catch people when they’re asymptomatic before they have a chance to spread,” explained Tuft’s President Anthony Monaco.Tufts plan for the fall is as complex as the virus itself. Students from outside the Northeast will be brought back to campus first, where they will be forced to quarantine for 14 days. Health officials expect at least a small portion of those students to test positive for COVID-19 the moment they step back on campus. Because of that, the university has constructed an extra 200 modular units of dorm space. The idea of the modular facilities is to give campus health officials a contained area to monitor students who test positive for the virus, while at the same time, keeping them out of the general population.After students from outside the Northeast are brought back to campus, students from the general area around New England will return.Every single student will be tested twice a week for COVID-19, something experts say will be a key component to safely reopening college campuses this fall. Regardless, school officials expect students to test positive for the virus throughout the fall.Researchers at Yale’s School of Public Health have been advising Tufts and hundreds of other colleges who are planning to resume some form of in-person learning this fall.“If we don’t test frequently, we give silent spreaders an opportunity to grab hold and this virus is hard to play catch-up with,” explained Professor A. David Paltiel, who recently published a study on how quickly the virus can spread through colleges if left unchecked.To study the virus, Paltiel and his colleagues used epidemic modeling to assemble hypothetical situations resembling a college campus. The study found that if you take 5,000 healthy students and add in only 10 students who have COVID-19, hundreds, if not thousands, of kids will be sick by Thanksgiving.“At that point, the only thing that keeps the virus from getting out of control is Thanksgiving break,” he said.That is why testing is key, the study found. When Paltiel took those same 5,000 kids and added in 10 students who have COVID-10, but tested every student twice a week, the study found that only about 100 students ended up catching COVID.“Many universities are planning to only test students who have symptoms, in our view that is a recipe for disaster,” he said.Only adding to the uncertainty of the situation, about 40 percent of college students said they would return to live near campus even if classes were held virtually. Paltiel and other health officials say because of that, it’s more beneficial to have students on-campus where they can be monitored and tested frequently.“It’s hard and it could be a nightmare, people who say we shouldn’t open campuses should remember the nightmare doesn’t go away,” he said. 3420
